(a-d) The Western Australia Police Force cannot provide a response to these questions as the recording of offences for possession of a prohibited drug under Section 6 or cultivating a prohibited plant under section 7 of the Misuse of Drugs Act 1981 in the WA Police Force Incident Management System or Prosecution Application do not specify the particular drug or plant type. Determining the number of charges relating to each specific prohibited drug or plant would require manual data interrogation and would be extremely resource intensive.
e)
i. Although only weight has been requested, the WA Police Force has also provided the drug types by other units of measurements:
